摘要
根据对淤泥质粘土和饱和砂进行的土动力学性质试验研究和应力波传播试验研究的成果，提供了一个饱和土应力波传播的新的理论计算方法。试验证明，饱和土属于应变硬化介质，在激波动力加载条件下，土中应力波将保持其激波特征不变。本文采用粘塑性模型和激波装配法建立了饱和土应力波传播的精确计算方法。
On the basis of the findings of the test research of both stress wave propagation and soil dynamics properties carried out in both the silt and the saturated sand.A new theoretical calculation technique is presented.The tests prove that saturated soils are a kind of strain hardened media and stress wave will maintain shock wave characteristic invariant during shock wave dynamic loading.An accurete calculalion method of the saturated soils with visco plastic model and shock fitting technique have been given in this paper.
